Detailed Description

Functions related to attributes, weight, experience, which concern only living things.

Todo:
make "stat"/"attr" coherent.

Macro Definition Documentation

◆ ADD_EXP

#define ADD_EXP (   exptotal,
  exp 
)    do { exptotal += exp; if (exptotal > MAX_EXPERIENCE) exptotal = MAX_EXPERIENCE; } while (0)

Handy little macro that adds exp and keeps it within bounds. Since we are now using 64 bit values, I'm not all concerned about overflow issues with exptotal wrapping. exptotal is typically op->exp, or op->total_exp

Definition at line 41 of file living.cpp.

◆ ADD_TOTALEXP

#define ADD_TOTALEXP (   exptotal,
  exp 
)    do { exptotal += exp; if (exptotal > MAX_TOTAL_EXPERIENCE) exptotal = MAX_TOTAL_EXPERIENCE; } while(0)

Definition at line 42 of file living.cpp.

◆ DIFF_MSG

#define DIFF_MSG (   flag,
  subtype1,
  subtype2,
  msg1,
  msg2 
)    draw_ext_info(NDI_UNIQUE, 0, op, MSG_TYPE_ATTRIBUTE, (flag > 0) ? subtype1 : subtype2, (flag > 0) ? msg1 : msg2);

Rather than having a whole bunch of if (flag) draw.. else _draw, make this macro to clean those up. Not usuable outside change_abil function since some of the values passed to draw_ext_info are hardcoded.

Definition at line 369 of file living.cpp.

◆ FLOAT_CON_BONUS

#define FLOAT_CON_BONUS   0

This is basically same as above, but for bonuses in which we store the value as a float.

Definition at line 85 of file living.cpp.

◆ FLOAT_DEX_BONUS

#define FLOAT_DEX_BONUS   1

Definition at line 86 of file living.cpp.

◆ FLOAT_GRACE_BONUS

#define FLOAT_GRACE_BONUS   3

Definition at line 88 of file living.cpp.

◆ FLOAT_SP_BONUS

#define FLOAT_SP_BONUS   2

Definition at line 87 of file living.cpp.

◆ INT_CHA_BONUS

#define INT_CHA_BONUS   4

Definition at line 62 of file living.cpp.

◆ INT_CLERIC_CHANCE

#define INT_CLERIC_CHANCE   2

Definition at line 60 of file living.cpp.

◆ INT_DAM_BONUS

#define INT_DAM_BONUS   6

Definition at line 64 of file living.cpp.

◆ INT_DEX_BONUS

#define INT_DEX_BONUS   5

Definition at line 63 of file living.cpp.

◆ INT_FEAR_BONUS

#define INT_FEAR_BONUS   0

The definitions below are indexes into the bonuses[] array. Rather than have a bunch of different variables, it is easier to just have a single array - all access to these is done through the get_cha_...() function in any case - making it an array makes processing simpler.

The INT_ prefix is to note the type of array the bonus goes into (vs FLOAT) - it is unfortunately that it is also the name of one of the stats.

The NUM_BONUSES is how many bonuses they are (size of the array), so is equal to last value +1.

Definition at line 58 of file living.cpp.

◆ INT_LEARN_SPELL

#define INT_LEARN_SPELL   3

Definition at line 61 of file living.cpp.

◆ INT_THAC0_BONUS

#define INT_THAC0_BONUS   7

Definition at line 65 of file living.cpp.

◆ INT_TURN_BONUS

#define INT_TURN_BONUS   1

Definition at line 59 of file living.cpp.

◆ INT_WEIGHT_LIMIT

#define INT_WEIGHT_LIMIT   8

Definition at line 66 of file living.cpp.

◆ MAX_EXPERIENCE

#define MAX_EXPERIENCE   levels[settings.max_level]

Definition at line 99 of file living.cpp.

◆ MAX_SAVE_LEVEL

#define MAX_SAVE_LEVEL   110

Definition at line 103 of file living.cpp.

◆ NUM_FLOAT_BONUSES

#define NUM_FLOAT_BONUSES   4

Definition at line 89 of file living.cpp.

◆ NUM_INT_BONUSES

#define NUM_INT_BONUSES   9

Definition at line 67 of file living.cpp.

Function Documentation

◆ add_player_exp()

static void add_player_exp ( object op,
int64_t  exp,
const char *  skill_name,
int  flag 
)
static

Add experience to a player - exp should only be positive. Updates permanent exp for the skill we are adding to.

Parameters
opobject we add exp to.
expexperience to gain. Can be 0, but not that useful to call in that case...
skill_nameskill to add exp to. Can be NULL, in which case exp increases the players general total, but not any particular skill.
flagwhat to do if the player doesn't have the skill. Combination of SK_EXP_xxx flags.

◆ add_statbonus()

void add_statbonus ( object op)

Adds stat-bonuses given by the class which the player has chosen.

Parameters
opobject which must be a player with contr not NULL.

◆ allowed_class()

int allowed_class ( const object op)

Returns true if the given player is a legal class. The function to add and remove class-bonuses to the stats doesn't check if the stat becomes negative, thus this function merely checks that all stats are 1 or more, and returns false otherwise.

Parameters
opobject to check.
Returns
1 if allowed, 0 else.

◆ apply_death_exp_penalty()

void apply_death_exp_penalty ( object op)

Applies a death penalty experience, the size of this is defined by the settings death_penalty_percentage and death_penalty_levels, and by the amount of permenent experience, whichever gives the lowest loss.

Parameters
opvictim of the penalty. Must not be NULL.

◆ calc_perm_exp()

void calc_perm_exp ( object op)

Ensure that the permanent experience requirements in an exp object are met. This really just checks 'op to make sure the perm_exp value is within proper range. Note that the checking of what is passed through has been reduced. Since there is now a proper field for perm_exp, this can now work on a much larger set of objects.

Parameters
opobject to check.

◆ change_abil()

int change_abil ( object op,
object tmp 
)

Permanently alters an object's stats/flags based on another object.

Returns
1 if we sucessfully changed a stat, 0 if nothing was changed.
Note
flag is set to 1 if we are applying the object, -1 if we are removing the object.
It is the calling functions responsibilty to check to see if the object can be applied or not. The main purpose of calling this function is the messages that are displayed - fix_object should really always be called after this when removing an object - that is because it is impossible to know if some object is the only source of an attacktype or spell attunement, so this function will clear the bits, but the player may still have some other object that gives them that ability.
Todo:
check logic, and things like that. Is the call to fix_object always required?

Parameters
statsitem to modify. Must not be NULL.
attrattribute to change.
valuedelta (can be positive).
Todo:
check if attr is valid? Checks result valus is valid?

◆ change_exp()

void change_exp ( object op,
int64_t  exp,
const char *  skill_name,
int  flag 
)

Changes experience to a player/monster. This does bounds checking to make sure we don't overflow the max exp.

The exp passed is typically not modified much by this function - it is assumed the caller has modified the exp as needed. skill_name is the skill that should get the exp added. flag is what to do if player doesn't have the skill. these last two values are only used for players.

Parameters
opvictim to alter.
expexperience to gain (positive) or lose (negative).
skill_nameskill to change. Can be NULL.
flag
  • if experience gain, what to do if player doesn't have the skill
  • if experience loss, whether to remove from all skills or only specified skill

This function checks to make sure that object 'op' can lose 'exp' experience. It basically makes adjustments based on permanent exp and the like. This function should always be used for losing experience - the 'exp' value passed should be positive - this is the amount that should get subtract from the player.

Parameters
opobject from which to subtract.
expexperience to lose.
Returns
the amount of exp object 'op' can in fact lose -

Ensures that all stats (str/dex/con/wis/cha/int) are within the passed in range of min_stat and max_stat. Often, the caller will pass in MIN_STAT and MAX_STAT, but in case of force objects or temporary calculations, we want things outside the range (force objects may have negative stats, but we don't want them too negative)

Given the skill name skill_name, we find the skill archetype/object, set appropriate values, and insert it into the object (op) that is passed.

We return the skill - this makes it easier for calling functions that want to do something with it immediately.

Parameters
opobject to which to give the skill. Must not be NULL.
skill_nameskill to give. Must not be NULL.
Returns
newly created skill, or NULL if failure (logger with error level).
Note
this doesn't check whether the object already has the skill or not.

Will tell the player about changed levels. A single call will handle mutiple level changes to one object from one effect. The only difference between this and the recursive version is this cannot handle a level that both increases and decreases simultaneously.

Parameters
whoplayer, must not be NULL.
opwhat we are checking to gain the level (eg, skill), can be NULL.

Gives experience to a player/monster, sharing it with party if applicable. This does bounds checking to make sure we don't overflow the max exp.

The exp passed is typically not modified much by this function - it is assumed the caller has modified the exp as needed.

This is merely a wrapper for change_exp().

Parameters
opvictim to alter.
expexperience to gain (positive) or lose (negative).
skillskill to change. Can be NULL.
flag
  • if experience gain, what to do if player doesn't have the skill
  • if experience loss, whether to remove from all skills or only specified skill

static void subtract_player_exp ( object op,

Subtracts experience from player.

Eg, if we figure the player is losing 10% of his total exp, what happens is he loses 10% from all his skills. Note that if permanent exp is used, player may not in fact lose as much as listed. Eg, if player has gotten reduced to the point where everything is at the minimum perm exp, he would lose nothing.

Parameters
opvictim we want to substract from
expvalue to substract. Should be positive.
skillskill to substract exp from. Can be NULL.
flagif SK_SUBTRACT_SKILL_EXP and skill is set, only subtract from the matching skill. Otherwise, this subtracts a portion from all skills the player has.
Todo:
check whether flag is necessary, can't it be only based on skill==null?
